Kerr/McNeillie in Dumfries

I am searching for any information about my gg-grandmother:

Rachel Kerr - born 1822 in Johnstone, Dumfries.
She died on May 25, 1880 in Port Hope, Ontario, Canada.
She married James Richardson McNeillie in Johnstonebridge, Dumfries on Nov. 24, 1843.

I don't know who her parents were or if she had any siblings.
Thank you,

Wendy - Rachel Kerr's parents were Thomas Kerr b. Torthorwald, Dumfries in 1776 d. 18 Mar 1853 in Kirkgunzeon, Kirkcudbrightshire. His wife was Isabella Currie b.abt 1784 Lochrutton, Kirkgunzeon, Kirkcudbrightshire. They had the following children: James b. 1807; Jane b. 1809; unknown daughter b. 1811; Rachel 1813-1880; Isabella b. 1815; Adam 1819-1846; and Thomas 1821-1850. You can find more details on McNeillie family tree at Ancestry.com (to which you have a pass).
